Mira

Overview

Orbital transfer and hosting spacecraft built for aggressive maneuvering, marketed as the most maneuverable vehicle on orbit. It delivers, deploys, and hosts payloads across LEO, MEO, GEO, and cislunar space.

Flight proven across three missions since November 2023. The debut flight raised its orbit 150 km in 75 seconds. Mira has now completed two close-proximity campaigns: the December 2025 Remora autonomous rendezvous (LEO-2 to ~1,250 m of LEO-1) and a July 2026 flyby in which LEO-2 closed to less than 200 meters of LEO-3. A fourth Impulse-only checkout, LEO Express 4, is manifested on SpaceX Bandwagon-5 and has not launched. Bookable with a 12-month lead time.
